spring系列之1--IDEA Spring mvc maven 工程

准备工作：
IDEA 14编辑器、Maven项目管理器、Tomcat容器

一、新建maven工程
(1) File->New->Project->Maven->Create from archetype(maven-archetype-webapp)  点击"Next"
(2) 输入GroupId、ArtifactId、Version 点击"Next"
(3) 选择Maven版本、配置文件、仓库地址  点击"Next"
(4) 输入Project name  点击"Finish"
注：第2步输入的GroupId、ArtifactId会体现在pom.xml中，由GroupId和ArtifactId来确定唯一的项目。第4步输入的Project name会体现在顶级文件夹名（项目名）上。

二、配置Tomcat
(1) Run->Edit Configurations->"+"->Tomcat Server(Local)
(2) 输入Name
(3) Server选项卡保留默认值
(4) Deployment选项卡->"+"->"Artifact…"->"ArtifactId:war exploded"->OK
注：如果第4步没有"Artifact…"选择，则直接保存现有的配置，然后右键"pom.xml"->Maven->Reimport重新引入下maven文件，再编辑Tomcat，Deployment选项卡就出现了"Artifact…"

三、项目结构
最后文件夹结构如下图所示：

其中，".idea"文件夹是IDEA编辑器自带的文件夹，可忽略。

四、配置spring库maven

在pom.xml里加入：

	<properties>
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
		<spring.version>3.1.2.RELEASE</spring.version>
		<mysql.verison>5.1.6</mysql.verison>
		<c3p0.verison>0.9.1.2</c3p0.verison>
		<ibatis.verison>2.3.0</ibatis.verison>
		<log4j.verison>1.2.16</log4j.verison>
		<servlet.version>2.4</servlet.version>
	</properties>

	<dependencies>
		<dependency>
			<groupId>junit</groupId>
			<artifactId>junit</artifactId>
			<version>3.8.1</version>
		<scope>test</scope>
		</dependency>

		<!-- spring start -->
		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-core</artifactId>
			<version>${spring.version}</version>
		</dependency>
		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-beans</artifactId>
			<version>${spring.version}</version>
		</dependency>
		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-web</artifactId>
			<version>${spring.version}</version>
		</dependency>
		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-webmvc</artifactId>
			<version>${spring.version}</version>
		</dependency>
		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-orm</artifactId>
			<version>${spring.version}</version>
		</dependency>
		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-jdbc</artifactId>
			<version>${spring.version}</version>
		</dependency>
		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-aop</artifactId>
			<version>${spring.version}</version>
		</dependency>
		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-context</artifactId>
			<version>${spring.version}</version>
		</dependency>
		<!-- spring end -->
	</dependencies>

五、配置web.xml

在webapp/WEB-INF/web.xml下加入：

<servlet>  
    <servlet-name>SpringMVC</servlet-name>  
    <servlet-class>  
        org.springframework.web.servlet.DispatcherServlet  
    </servlet-class>  
    <init-param>  
        <param-name>contextConfigLocation</param-name>  
        <param-value>classpath:/spring-core.xml</param-value>  
    </init-param>  
    <load-on-startup>1</load-on-startup>  
</servlet>  
  
<servlet-mapping>  
    <servlet-name>SpringMVC</servlet-name>  
    <url-pattern>/</url-pattern>  
</servlet-mapping>  

六、配置spring

在resources文件夹下建立一个名为spring-core.xml的文件，文件名和地址是由web.xml里<init-param><param-name>为contextConfigLocation的<param-value>决定的。

<?xml version="1.0" encoding="UTF-8"?>  
<beans xmlns="http://www.springframework.org/schema/beans"  
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"  
    xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"  
       xmlns:p="http://www.springframework.org/schema/p"  
       xsi:schemaLocation="http://www.springframework.org/schema/beans  
    http://www.springframework.org/schema/beans/spring-beans-2.5.xsd  
    http://www.springframework.org/schema/context

    http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd  
    http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd"  
    default-autowire="byName">  
</beans>
